The refrigerator is not cooling. I have the EG3 model. It's plugged in and electric is going to the unit. The thermostat is at mid rage position, it is selected as electric, and on AC position. There is DC current going to refrigerator as evidenced by the inside light is working.

After it's plugged in I can hear the liquid start to boil but no cooling occurs.

What is the model number of your refrigerator. The EG3 after the model number indicates that it is a 3 way (propane, 120 v and 12v).
Is the freezer getting cold but not the refrigerator. If so that is a sign of blockage in the tubes by being operated off level.
If nothing is getting cold and you are operating on electric your 120 volt heating element might be going bad. It is an easy replacement.

Is it cooling on propane?

The model # is 876EG3. The manual talks about a possible blockage from operating it off level. It says to lay it on its LEFT side for a minimum of one hour to allow the ammonia and water to mix with one another. Which is the left side ?? If I am facing the doors is the left the same as my left ?? If I am facing the back of the refrigerator then the left is the other side.

I have it plugged in and I can hear the fluid boiling. The heat goes up the tube along the flue and into the fins at the top. The coils on the lower half of the refrigerator also are hot. It sounds like the fluid is boiling and seems to be circulating but no cooling.

I tried the gas system and I get the same results.

Well, I laid the refrigerator on it's side, the side with flame when you light the gas I assumed it is the left side, over night. Just stood it up and plugged it in and now waiting to see if it will cool. I hope so.

Tom,
I may be wrong which happens often, but from my experience when I am trying to figure which is right or left side of something, then I relate it to if that item was me. For example, on gmc or any car, the right side is the passenger side. For a fridge, If I was inside it looking out the door, the door is front and the right side is same as the left side if I am outside of fridge and I was facing fridge. or maybe relate it to if I was behind the fridge looking in same direction it is looking.
either way, I do wish you luck

Makes sense to me. If it doesn't work now I will lay it on the other side, the side you said is the left, and try it again. One of these should work. The thing was working at the time I stored the GMC two years ago, so should still work. I can find no damage or chew or broken wires. It fires up on gas and electric. The condenser and absorber tubes get hot, just waiting for cool inside.

Hey Tom;

I've always pulled the refrigerator out and turned it up-side down.
I leave it like that overnight then put it back in. I've done this
with three different refers in 3 different coaches (I'm about to do it
to the refer in my SOB). The problem is that I don't have a level
place to park my coach so overtime the refer just looses it's cool.
Anyway, it has worked for me.

A Dometic RM 763 out of my daughter's coach did not work, so it's been
upside down since May. Turned it right side up yesterday and hooked a 12v
battery to it and plugged it in. It gurgled for 4 hours, the electric
heater seemed to be working, never did cool. After I unplugged it, I could
here the 12v ignitor trying to start (no LP hooked up). Disconnected the
battery, now looking for a replacement (and that is the Dometic RM 2620 or
may just buy the whole cooling unit for about half the price of a new one).

Tom,

"The manual talks about a possible blockage from operating it off level. It says to lay it on [ITS LEFT SIDE] for a minimum of one hour to allow the ammonia and water to mix with one another. Which is the left side ?? If I am facing the doors is the left the same as my left ?? If I am facing the back of the refrigerator then the left is the other side"

From the manuals wording bracketed above, they say its left side so place yourself in the refrigerators place and now your left is the reefers left.

Hope it works.

I just plugged it back in after laying it on the other side for 4 1/2 hours. If that don't work then I think I will try the upside down thing tonight like you said works for you. Will keep you posted.

Well it's been 4 hours and the fluid is hot and sounds like it is circulating but still not cooling. Unplugged it and it is now upside down for the night. I will plug it in tomorrow and hope for cooling.

Lay it on the side the pilot light is on. This worked with my norcold the the first time then a couple of months later it stopped cooling again.This time laying it on its side didn't work so I replaced it with a Dometic Americana that was slightly larger on the outside but 1 shelf bigger inside. For me it was a nice improvement.

Well, upside down did not work. Gonna try on the pilot light side this time. Anyone know what kind of blockage could be in it ?? What is the blockage made of since there is only water, ammonia, hydrogen in the system??

If this is ammonia crystals, does this only happen when running off level, or is this something that is just going to happen no matter what.
For a camper used 3 to 5 long weekends a year, is it best to run fridge the same as genny which is every other month for 30 to 45 minutes?

Just operate it when you need it and try not to operate off level when you aren't moving. The crystals come from being too far off level. A little bit is ok. Try to keep the bubble part way into the bullseye with it located in the freezer metal plate area. I am talking about the little round bubble level you should have?

It is not ammonia crystals. It is a chromate from the corrosion inhibitors that are in the system and which has been overheated. It will not redissolve as ammonia crystals might so the process is irreversible. Turning the refrigerator on its side or top may temporary dislodge the blockage but it usually doesn't last long before it reclogs.

All great info. I know and understand more about this system than when I started. I left it on its side overnight and have now plugged it back in. Hopefully it will start to cool. If not I guess I have a clogged system that will have to be replaced since the crystals won't dissolve. I am going to hope for cooling. Laughing
